JVENT IL AT ING APPARATUS 1929. serial N5. 354,751. l

proved ventilating apparatus comprises a receptacle 1 provided with an opentop which is closed by a removable, air-tight cover 2. The interior of the receptacle 1 is divided into a primary chamber 3*anda secondary chain ber 4, by a partition wall 5, whichis disposed transversely and extends vertically. The partition wall 5 is fixed to the bottomand side walls of the receptacle "1 and the upper end thereof projects into-a hood 6,-which is fixed to the topof the cover 2. The only communication between the primary and secondary chambers 3 and 4 is throughthe hood 6 over the upper end of the partition wall 5, which is spaced from the top ofthe hood 6 to provide a passage therebetween. j

primarycooling coil 7 is mounted in the primary chamber 3 and a similarcooling coil 8 is mounted in the secondary chamber 4, Theinl'etends ofthe cooling coils 7 and 8 connect, and communicate with a common inlet conduit 9 and are provided with respective control valves 10 and 11. The outlet ends of the cooling coils 7 and 8 connect and communicate with the outlet conduit 12, as in- The inletand outlet conduits 9 and 12 are adapted for connection with any suitable. me-

chanical refrigerating unit of the type now' in common use for cooling associated coils to a desired low temperature for refrigerating purposes. No claim is made to any particular mechanical refrigerating unit except for the specific arrangement of the associated coils 7 and 8 as embodied in the present invention.

A plurality of spaced, transversely extend ing and vertically disposed bafile plates 14 are fixedly carried b the cover 2 and depend into respective cham ers 3 and .4. A plurality of similarly disposed bafile plates 15'are fixed to the bottomof the receptacle 1. i

The baflie plates 14: and 15 are disposed in staggeredrelation with respect toeach other, and extend into the bends forming respective cooling coils 7 and 8, thelower ends of the ballle plates 14 being spaced from the bottom of the receptacle 1 and the upper ends of the baffle plates being spaced from the cover 2.

The prin'iary chamber 3 carries a supply of liquid 16, preferably water mixed with some suitable, non-corrosive chemical agent to prevent the possibility of freezing the water by the temperature of the primary coil 7, which has the greater portion thereof submerged in the liquid 16.

The cover 2 is provided with an inlet plug 17 for supplying or replenishing the liquid 16 in the primary chamber 3. The receptacle 1 carries a gauge 18 which registers the level ofthe liquid 16, and embodies a drain valve 18 for draining the liquid 16 from the primary chamber 3 when required. The baffle plates 15 in the primary chamber 3 are formed with apertures 19, which are disposed adjacent to the bottom of the receptacle 1, and provided to allow the draining of the chamber 3, in the manner herein stated; 7

No liquid is carried in the chamber 4, and

the secondary coil 8 in the latter virtually constitutes a condenser for dehydrating the air on its passage through the said chamber 4. A cup 20, provided with a drain cock 21, is fixed to the bottom of the receptacle 1 and communicates with the chamber 4 for collecting potential drippings from the operation of the condenser coil 8. The baffle plates 15 in the secondary chamber 4 are formed with apertures 22, which are disposed adjacent to the bottom of the receptacle 1 to permit the draining of the chamber 4 of dripping, as herein set forth.

Figure 2 illustrates the embodiment of our improved ventilating apparatus as functioning through a hot air type of heating furnace. An air outlet conduit 23 establishes communication between the secondary chamber 4 and the distributing dome 24 of any ordinary hot air type of heating furnace. The outlet conduit 23 connects with the cover 2 and communicates with the chamber 4 at a point between the end wall of the receptacle 1 and the baffle plate 14 which is adjacent to said end wall.

Air is supplied to the ventilating apparatus through an inlet conduit 25 which connects with the cover 2 and communicates with the primary chamber 3 at a point between the other end wall of the receptacle 1 and the bafiie plate 14 which is adjacent to said end wall.

The air is driven through the ventilating apparatus by a power operated blower 26, as shown, which is connected with the inlet conduit 25. It will, of course, be obvious that the latter may connect with an air storage reservoir providing the desired air pressure to operate the ventilating apparatus, instead of employing the blower 26, as stated. The air supply may be drawn from the enclosures being ventilated or from a fresh source of supply.

In practice the operation of our improved ventilating apparatus, when used in connection with a hot air type of heating system, is as follows :-The operation of the blower 26 will force the air into the primary chamber 3, through the liquid 16, downward and upward between the baffle plates 14 and 15 and along the entire length of the primary coil 7. As the temperature of the latter and of the liquid 16 is very low, the air on its passage through the primary chamber 3 in the manner stated, will become chilled.- Further the forced passage of the air through the liquid 16 will remove all impurities therefrom.

The chilled air now passes from the primary chamber 3 through the hood 6 and over the top of the partition wall 5 into the secondary chamber 4. The air passes around the baffle plates 14 and 15 in the secondary chamber 4 and along the secondary coil 8, which still further chills the air to the temperature desired and prepares same for distribution. The air is now forced from the secondary chamber 4 into the furnace dome 24 through the outlet conduit 23. The chilled air is driven from the furnace dome 24 by its normal operating pressure and is distributed to the various rooms of the building structure through the usual warm air pipes connected with the furnace dome 24 in the manner identical to their function when employed for distributing hot air in the usual manner.

It will be apparent that the air may be distributed without utilizing the distributing ducts of a hot air heating system, by providing special distributing conduits therefor. However, the heat distributing ducts of a hot air heating system are admirably adapted for distributing the cool air as described. It is. of course, intended to operate the cooling and ventilating device only during the seasons in which the heating system is not required for heating purposes.

The control and operation of the secondary coil. 8 regulates the humidity of the cooled air before the same is distributed. An excessive amount of moisture in the air might result in unhealthful conditions and dampness. I t might also cause condensation on the interior of the distributing ducts, causing rust or corrosion.

Figure 3 illustrates a modified form of ventilating and cooling system which is designed for use in connection with heating system employing water, vapor and the like through radiators in the usual manner.

The device comprises a cooling coil 27 mounted in a closed water receptacle 28. The coil 27 is identical in construction and operation as the primary coil 7, herein described, and is provided with an inlet connection 29, including a control valve 29, and with an outlet connection 30. The receptacle 28 is ing coil 27, whereby the radiators will be also provided with a plurality of bafiie plates 31, which are arranged in a manner identical to that described relatively, to the preferred form.

A pump 32 isemployed for circulating water through the receptacle 28 and through the radiators oi the heating system with which the device is connected. A conduit 33 communicably connects the one end of the a receptacle 28 with the pump 32, and a pipe 34 connects the latter with one end of the radiatorfinstallation. yAnother pipe35 conneots the other end-ofthe radiator installation with the other end ofthe receptacle 28. f

It will be evident that theoperation of the pump. 32 will continually circulate'the tures,
